Application filed August 18, 1914. Serial No. 857,354.

To all whomy t may concern: f

De it known that I, HENRY J. STUART, a citizen of the United States,residing at Derby, in the county of New I-Iaven and State ofConnecticut, have invented a certain new and useful Improvement in Loopand Button Clasps, of which the following is a specification.

VMy invention relates to button clasps for garment supporters and likearticles, but more particularly to that class of the same in which thebutton is provided with an elastic collet.

The object of my invention is to provide a button having an elasticcollet and a tapecovered base plate which can be economically andquickly assembled.

I vattain this and other objects of my invention in the device set forthin the following description and accompanying drawings in which likereference characters refer to corresponding parts.

In the drawings:

Figure l is a front view of the lower extremity of a hose supporter;

Fig. 2, a central longitudinal sectional view thereof;

Fig. 3, detail views of the rubber collet forming the head and shank ofthe button;

Fig. 4, a top plan view of the button base and stud;

Fig. 5, a front view of a fragmentary portion of the apertured tab;

Fig. 6, a side view of the base and stud showing the tab secured to thestud, and

Fig. 7, a side view of the button after its arts have been assembled.

The button clasp, which is shown depending from a fold in the extremityof the supporting strap A, consists of an attaching link B, a buttonloop C, and a button take or tab D which carries a button E at itsVlower extremity. The button loop C, which is connected to the lower sideof the link B by a lip F projecting from the upper side thereof, isprovided with a bridge Gr and has the sides of its lower extremitycontracted to engage the shank of the button E. Vith the exception ofthe button E the device thus far described is one of the common forms ofloop and button clasps well known in the art. Referring to Figs. 1 to 7inclusive, in Vwhich. the parts are shown enlarged the button E consistsof ametal base D. Projecting outwardly and riveted to the base 2 is awire stud 3. The stud 3 is headed to form a convex cap 4, which ispreferably annularly recessed on its under side, to form a peripheralbiting edge 5. The elastic rubber collet 6 is shaped to form a head 7and a shank 8. The collet 6 is provided with a central aperture 9 havingan inside cylindrical wall 10 flared outwardly at its upper extremity.The diameter of the wall 10 is less than that of the head 4 andpreferably less than that of the stud 3. One extremity of the tab D ispunched, before it is applied to the button, to form an aperture 11.

. To assemble the button, the stud 3 is first riveted to the base 2.'Ihen the apertured extremity of the tab D is slipped over the head 4 ofthe stud, or to be more exact the head 4 is slipped through the aperture11 in the extremity of the tab, thereby securing the tab to the stud sothat its upper end 12 will slightly overlap one end of the base 2, asshown in Fig. 6. The rubber collet is then sprung over the stud by rstplacing the under side of its shank 13 against the head 4 then pressingdown causing the head to distort the rubber in the wall 10 of theaperture as the collet passes down on the stud. The pressure of thecollet is continued until the under side of its shank 13 presses theedges of the aperture 11 in the tab hard against the front face of thebase 2. The vertical dimension of the collet and stud are preferably soarranged relatively to each other that, when the downward pressure onthe collet is relieved, the latter springs upwardly engaging theunderside of the head 4, and causes the peripheral edge 5 of the latterto become embedded in or bite into the flaring extremity of the wall 10of the aperture. In this manner the collet is held between the underside of the head of the stud and the top of the base, or to be moreexact the front of the tape-covered base, and coacts with the base toprevent displacement of the tab. The tab is then carried around in backof the base 2 and upwardly through the link B, then downwardly andrearwardly through the loop passing over the top of the bridge G. Theoverlapping ends 12 and 14 of the tab are then sewed together bystitches l5 immediately adjacent t0 the upper end of the base2,5th`e'e`nd 112 being folded in to form a. hem which prevents fraying.The button base, being confined between the layers of the 'tab 4whichare Wider than'the base, is entirely Covered and concealed, therebyobviating any disadvantages incident to the exposure 'of a metal part.It should be noticed that the eXpansive force 'exerted Iby the rubberforming the collet effects a grip Abetween the parts Which prevents themfrom becoming loose from Wear andi strain and also prevents them frombeing twisted out of longitudinal alinement. For this reason it is not`necessary to close the layers of the tape along the side edges of thebase. In the above description I have referred to thecollet as beingmade of spring or elastic rubber, yet I may employ a 'collet made out ofany other mate rial having characteristics which will enable it tobesprung on to a headed stud. Ipre fer, however, to employ `a colletmade of spring' rubber since it is the best material, so far as I amaware, to hold the parts together and'to grip the garment.

While the. preferred forms lof my invention are embodied in the devicesabove'described yet the same are susceptible to such modifications asmay fairly come Within the scope of the appended claims.

Having now described my invention What I desire to claimandprotect'byLetters Patent is:

l. In a ybutton clasp a button comprising a baseon vwhich is'mo'u'nted aheaded stud, the said base having its front Vsiderfcovered with4 tapewhich surrounds *the stud and a spring rubber collet surrounding saidstud 'in front of the tape and containing a passage therethrough of lessdiameter than'the head of the stud, the said collet being held againstthe tape by the under side of the head of the stud, and the saidstudpassing entirelythreugh said collet. f

2. In a button clasp a 4button 'having a base on which is mounted aheaded stud7 the said base having its frontside-covered With fabricmaterial through which saidstud e tends and an elastic collet slippedover the stud in front of the fabric material and containing a'passa'getherethroughI of less diameter thanthe head of the-stud, the said studpassing 'entirely thro'ugh `the collet `Which latter entirely fills thespace `between the front side of the fabric material and thc under sideof the headfofthe stud.

In Witness whereof I have hereunto s'et myhand on this-23rd day of July,1914.
